Anritsu FAQs
I am receiving a saturation warning on my MS272xB, MS271xB or MT8222A even though there are no large signals on the screen. Why is that happening and what can I do about it?
The presence of large signals, even if they are outside of the span range to which the instrument is set can cause mixer saturation and generate a warning so the user knows that measurement accuracy may be compromised. Increase input attenuation to reduce the amplitude of the signal into the instrument's circuits.
